Abstract:
A device for applying a mat of aggregate material having an entrained liquid additive as the device is moved along a path. The device includes a hopper for receiving the aggregate material, a spreader for spreading the aggregate material generally transversely relative to the path, a compacting screed for compacting the aggregate material into the mat, and a mixing conveyor arranged to convey the aggregate material from the hopper to the spreader and to mix the aggregate material along the length of the conveyor. A conduit in flow communication with an additive supply source is mounted within and spans a portion of the hopper. The conduit thus communicates the liquid additive from the additive source to the aggregate material as the aggregate material is being mixed and conveyed.
